Specification of Letters Patent.

Application filed March 16, 1911.

Patented Apr. 23, 1912.

Serial No. 614,811.

To all whom it may concern:

Be it known that I, THOMAS F. Cox, a citizen of the United States, residing at Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Tugboats, of which the following is a specification.

This invention relates to boats or vessels and more especially to that class known as tug-boats, and concerns principally the exterior form of the hull thereof.

The object of my invention is to provide a boat of this character which may be driven from either end, thus overcoming the well known difliculty experienced in an attempt to handle such boats when backing, and to further provide a hull of such form as to protect the rudder and propeller from damage incident to the character of work performed by such vessels.

The following description, read in connection with the accompanying drawings, will enable persons skilled in the art to which my invention relates to understand and to practice my invention in the form in which I employ it; but it will be understood that my invention is not limited to the precise form and details of construction herein illustrated and described, as the same may be changed or modified in various particulars without departing from the spirit of my invention and the scope of the claim.

Referring to said drawings: Figure 1 is a side elevation of a tug-boat constructed according to my idea. Fig. 2 is an enlarged detail view of the prow. Fig. 3 is a plan View of the main deck, cleared of all upper structure, the undercut being shown in dotted lines.

Referring to said drawings by numerals, the hull l tapers gradually toward either end where it terminates, the upper portion in the sharp overhanging prow 2 formed with a curved or rounded under portion 3, the lower portion of said hull tapering more rapidly as it nears the ends and terminating in the lower prow 4:- The curve of said under portion 3 is convex. here the overhanging portion of the sides of the upper hull meets the sides of the lower hull the curve is concave. The keel of the vessel is practically straight or horizontal. As can readily be seen, the formation of the overhang at the ends produces a positive protection for the rudder and propeller when the tug is running in between or alongside of tows.

It will be understood from the foregoing that this type of boat provides means whereby the rudders and propellers are so disposed that the ends 2 of the hull project well beyond the same both to the sides and forwardly and also that the bottoms of said ends are so shaped that while being in the water at all times, yet offer little or no resistance to the progress of the boat through the water.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is

A hull for double-ended power boats having overhanging ends that project beyond the rudders and propellers both laterally and longitudinally, the major portion of the hull terminating in straight vertical portions beneath the inner ends of the overhanging ends, the bottoms of the overhanging ends being rounded and converging toward the longitudinal center thereof and the rear ends of said bottoms merging into the or portion of the hull on easy curves adjacent the straight ends of said major portion.

In testimony whereof I hereunto aiiix my signature in presence of two witnesses.
